Biologists at the University of Southern California have discovered bacteria that can do without traditional sugar-based foods. Unusual bacteria consume and release ... pure electrons.
As you know, the human "energy reactor" works due to the interaction of sugar and oxygen. Sugar creates excess electrons, which are converted into oxygen during respiration, supplying us with the energy we need.
Electrical bacteria can do without sugar as an intermediary and consume electrons "directly". These bacteria have been found in ocean sediment. In the laboratory, a controlled electric current was passed through the sediment.
At higher voltages, the bacteria greedily “devoured” the electrons emanating from the electrode. When the voltage dropped, the bacteria "exhaled" electrons back onto the electrode, creating an electric current. In the future, these bacteria may become the basis for autonomous power supplies for nanoscale devices.
Some of these bacteria can form biocables or microbial nanowires, which can then self-assemble to form the electrical networks of the future.
